2.3.14 MKV Normal Quality profile converting 1920x1080 to 1920x1072

I'm running the 2.3.14 build from 10/21 and using the stock 'MKV Normal Quality' profile. My source files are OTA WTV recordings and contain MPEG-2 viedo and AC-3 audio. I'm not versed in ffmpeg options by any means, so I'm not sure if this is an issue
or working as designed, but all 1920x1080 files processed by this profile are resulting in 1920x1072 MKV files (h264/AC3). I don't have a log file to attach at the moment, but can later if needed. Or maybe an ffmpeg wizard can look at the profile options and
explain what's going on. Thanks.
